N9340B
Know your spectrum
Regardless of whether you are handling
military communications, a Wireless
Service Provider (WSP), or involved
with spectrum management you need
to avoid impaired communication.
The N9340B provides you with a reliable,
accurate and detailed picture of your
communication spectrum.
When you test, you need fast data
capture to help locate and identify
elusive, transient interference signals.Thats why every N9340B spectrum
analyzer has a truly fast sweep time.
It requires less time to measure across
the spectrum, to obtain more reliable
test results and to help you achieve
more for the same investment of time
and money.

Spurious signals and noise are of greatconcern to all network users. A superior
combination of low displayed average
noise level (DANL) and single sideband
(SSB) phase noise coupled with a
narrow resolution bandwidth (RBW)
means your signal measurements are
more reliable and you will have more
confidence in your test results. The
N9340Bs low DANL and SSB phase
noise helps you detect very low-level
signals (spurs or noise) which are close
to the carrier. You will avoid missing
these difficult-to-identify signals, whichwould otherwise lead to an insufficient
or even incorrect understanding of the
spectrum.
The N9340Bs RBW is the narrowest in its
class. The narrow 30 Hz bandwidth of the
analyzer ensures that it is even easier
to identify, resolve, and measure two
signals that are close together.
Additionally, with a resolution filter
shape-factor of less than 5, the N9340B
has the ability to resolve closely spaced
signals with unequal amplitudes.
Moreover, the narrow RBW means that
the spectrum analyzer introduces minimal
noise itself, helping to further reduce
DANL and improve sensitivity.
Superior sensitivity
With more wireless devices on the market
requiring greater bandwidth usage, the
ability to discriminate between different
signals becomes more challenging. Itsunder such demanding conditions that the
superior performance of an N9340B
analyzer proves its worth. The N9340B
has one of the best sensitivity and
selectivity specifications. The DANL is
124 dBm, or 144 dBm with the
optional preamplifier (30 Hz RBW, 10
MHz < fc < 1.5 GHz). The optional
preamplifier adds 20 dB gain for
improved analyzer sensitivity.
Speed at your fingertips
The RF spectrum is a finite resource,
therefore its usage requires management.
Most regulatory authorities responsible
for administering frequency allocation
require service suppliers and network
operators to perform routine
monitoring of signal power and
transmission frequency stability.

Spectrogram
Now you can takeadvantage of thespectrogram display to view thebehavior of
varying signalparameters over time. The
N9340Bincludes spectrogram as a standard
feature. The scrolling three-dimensional display
is noted for itsability to track the frequencyand
power behavior over the time, particularly
intermittent signals. Theuser canuse
spectrogram to analyze thestabilityof a signal
over thetime, or to identify intermittent
interference signals in communications systems.
There are twomarkers for theuser to identify
power versus frequencyandtime. Also the time
interval between two consecutive colored rows
can beadjusted. Whena marker is put on the
spectrogram, the N9340Bcan display the trace
for the timeof the selectedmarker.
Thespectrogram data andscreenshots canbe
savedand recalled for lateranalysis or reporting.
Extened spectrogram monitoring(Option INM)
Option INMextends the N9340B spectrogram
capability furtherwith the ability to continuously
monitor and save spectrogram data over time
not only to theanalyzers internal memory or a
USB flash drive, but also directly to a PC. With
option INM users can save more than 1,500
continuous frames of data depending on the
size of the USB flash drive or PC memory.
Option INMalso supports an Automatic Save
function. The N9340B can save the spectrogram
at a user specific timeor at a set interva ofl
frame..
All the small files with the same
prefix can be combined into one file using
N9340 PC Software, makinganalysis easier.
Theuser can choose among the 3 display
modes: spectrogram only, spectrum trace only
or thecombination of a spectrogram and a
spectrum trace in one screen. Limit lines with
pass/fail functionality is also available in this
measurement. The N9340B will identify the
failed frame of spectrogram data with a red
mark. The Pass/Fail test can also provide alerts.
Users may use marker to find theprevious/next
frame failed data to quickly find theoffending
event or interference. Thespectrogram data may
be playedback for reviewon either the analyzersdisplay or on a PC utilizing N9340B PC Software.
With the option INM, the Agilent N9340B
spectrum analyzer can provide unattended
monitoring of communication systems capturing
performance or intermittent events like
interference over extended periods of time
days rather than hours. Theoption INM can
provide additionalvalue for the wireless network
DSL measurements(Option XDM)
The spectrogram gives the three-dimensionaldisplay of power, frequency and time.
The N9340B INM shows spectrogram andspectrum traceon the samescreen.
important application of spectrum
N9340B is now equipped with powerful
features to address field applications
using a handheld spectrum analyzer. An
analysis is identifying interfering signals.
These often arise from illegal transmissions,
and may cause impairment of services for
authorized users, often resulting in financial
loss. These interfering signals could
possibly restrict critical communications
of civil aviation and emergency services,
which could jeopardize public safety.
Aerospace & Defence: radio and radar test, interference analysis,on-site repair
Wireless Service Providers: interference analysis, on-site repair
TV & Broadcasting: interference analysis, channel power check
Spectrum Management Authority: spectrum monitoring
N9340B Applications for Field Test
communication systemmanagers, hospital
administrators, etc. as well as police and
homeland security by recording spectrogram
measurement results over time.
xDSL (ADSL and VDSL) is widely used for
broadband internet connections at homes and
businesses. Service providers occasionally face
problems with interference on their xDSL lines.
The interference is mainly intermittent intrusion
from nearby external sources such as electric
motors, elevators, and appliances. In order to
monitor, capture and remove intermittent
interference, the engineer may need to work in
the field for extended periods of time.
With hardware option XDM the N9340B now
supports measurements on ADSL, ADSL2+ and
VDSL networks. It provides very good sensitivity
with low displayed average noise levels (DANL)
to meet themask requirements overADSL frequencyranges, from9 kHz to 12 MHz, for ADSL.

IBOC measurements(Option IBC)
Option IBC has built-in FCC and NRSC
(National RadioSystems Committee) spectral
emission masks for quick compliance
measurements with visual and audible
pass/fail indicators.
N9340B IBC also supports a one-button
auto-tune function that greatly simplifies the
otherwise complex user setup required to
capture and measure IBOC signals of interest.
The auto-tune function will automatically set
the frequency span, RBW, Average and
Detector types, etc. It only takes seconds for
the auto-tune function to display the correct
measurement results.
The included Channel list featureenables usersto easily create and recall setup and
measurementparameters for single or multiple
broadcast frequencies and channels. The user
no longer needs to spend time remembering
numerous channel setups but can simply load
the desired channel from the list to start a
measurement. The Channel list can be
loaded, copied and deleted.

Users may choose to make the xDSL
measurement in either spectrum analysis
or spectrogram mode. Using xDSL
measurement in spectrogram mode is ideal
for capturing intermittent interference on
xDSL lines. When used with option INM,
the DSL measurement application can
measure and record DSL performance data
to a USB flash drive or PC over hours or even
days.
An xDSL probe from Vierling is required to
connect the N9340B analyzer to xDSL
networks for measurements in the field.
N9340B is the industrys first handheld spectrum
analyzer with a dedicated IBOC measurement
mode. The option IBC is not available as an
upgrade and must be ordered at the time of
instrument purchase.

IBOC-FM measurement with N9340B IBC.
ADSL measurement with N9340B XDM
The option XDM is not available as an
upgrade and must be ordered at the time of
instrument purchase. The XDM option can
also be used for other applications whichrequire improved DANL and phase noise at
frequencies from 9 kHz to 12 MHz.
Option IBC equips the N9340B with in-band
on-channel (IBOC) measurement capability
through a dedicated measurement personality
and selected hardware improvements. IBOC
technology is a method of transmitting digital
and analog radio broadcast signals (AM and
FM) simultaneously on the same frequency.This HD Radio version of hybrid digital/
analog technology is the only one approved by
the FCC for U.S. radio broadcast stations.
The IBCoption adds enhanced SSB phase noise
for IBOC AM measurements and a noise
cancellation process for improved IBOC FM
measurement margins. IBOC-AM covers 530
kHz to 1.7 MHz and IBOC-FM covers the 87.5
MHz to 108 MHz frequencies.
